Definitions

  • the invention relates to a method for applying a grid-shaped adhesive coating of adhesive spots on a substrate and a device suitable for carrying out this method. Furthermore, the invention relates to substrates which can be produced by this method and are pressure-sensitive adhesive, the adhesive force of which can be adjusted from permanent adhesion to residue-free removal.
  • Pressure-sensitive, removable paper labels in particular sticky notes, have found widespread use.
  • an adhesive layer is applied to the back of the paper, possibly only on an edge area.
  • the adhesive layer can be formed from individual adhesive points which are not connected to one another, the number of these adhesive points being, for example, between 10 and 15,000 / cm 2 , which corresponds to an application of adhesive of approximately 1 to 30 g / m 2 .
  • a number of methods are used to produce such labels.
  • DE-A-33 46 100 describes the production of pressure-sensitive sheet-like structures which can be removed again without leaving any residue using a screen printing and a gravure printing process.
  • rotary screen printing a method which is particularly suitable for the application of adhesive dots, a printing squeegee is arranged stationary in a circular screen printing form which is closed on one side. The adhesive is fed into the interior of the stencil and by means of the squeegee through the perforation of the stencil wall onto the outer substrate web pressed. This creates an application of grid-shaped adhesive spots in accordance with the design of the template.
  • DE-B-11 31 079 describes a device for applying adhesives to paper webs.
  • a cell wheel is mounted in a mouthpiece serving to supply the adhesive, which allows the adhesive to be applied intermittently to a paper web running over a counter-roller.
  • the adhesive is supplied in each case and the disposition of the cellular wheel within the mouthpiece results in a uniformly interrupted application of glue.
  • controllable nozzles are used in their opening and closing, which either rest on the surface of the goods or are at a distance of at most 2 mm from the surface of the goods.
  • DE-B-1 288 077 describes a method for the punctiform application of adhesive and the like. onto a material web guided past an adhesive outlet opening, underneath a template provided with cutouts and moving in synchronism with it. The process is not carried out without contact, i.e. the paper web is pressed against the edge of the doctor blade either by the web tension itself or by an elastic pressure roller or other pressure devices together with the application film.
  • the invention has for its object to provide a method for applying adhesive spots on a substrate, which can be adapted to different substrate specifications, such as different substrate material, without great technical effort, and a different adhesive force from permanent adhesive to residue-free removable, can adjust, the disadvantages occurring in the known methods are avoided.
  • the method is said to be particularly applicable to the manufacture of labels.
  • This object is achieved according to the invention by the method for the contactless application of adhesive spots on a substrate.
  • adhesive is pressed under pressure through fine nozzles, which can optionally be arranged in a block at the same time, a band provided with recesses past the openings of the nozzles, the nozzles being periodically opened and closed.
  • the adhesive emerging from the nozzle opening as a continuous thread is cut into fine particles which continue to move in the exit direction without contact.
  • a substrate is passed under the nozzles or the nozzle block, preferably at right angles to the band provided with recesses, on which the adhesive particles are collected and form a grid of adhesive points.
  • the distance between the adhesive points of the grid-like coated substrate and the base diameter of the adhesive points play a role in the achievable adhesive force and the residue-free detachability of the substrates.
  • the base diameter and the spacing of the adhesive points can be precisely controlled in a technically simple manner.
  • the adhesive particles which emerge periodically through the circumferential band provided with recesses can form after exiting into fine spherical adhesive droplets which, after striking the paper, result in spherical adhesive dots.
  • a suitable choice of the substrate feed or the feed of the tape can also be used to produce adhesive spots in oval or ellipsoidal design.
  • a grid of adhesive dots with precisely defined properties and dimensions can be achieved.
  • a distance of the substrate from the underside of the band provided with recesses of 0.1 to 5.0 mm, preferably 1.0 to 2 mm, has proven to be favorable for the formation of spherical droplets of adhesive.
  • the shape and exit direction of the adhesive particles also depends on the manner in which the adhesive is divided by the circumferential band, the lowest possible force being exerted on the adhesive thread in the direction of movement of the band when the adhesive is separated.
  • the edge of the recess on the side of the band facing the nozzle openings is advantageously designed such that a phase angle between 5 and 17 ° is set, which can be varied slightly depending on the viscosity of the adhesive. A particularly favorable angle is between 9 and 12 °.
  • the feed speed of the tape provided with recesses also influences the shape of the adhesive points and is expediently in the range from 50 to 400 m / min.
  • the height of the adhesive spots is also influenced by the pressure with which the adhesive is supplied to the nozzle block.
  • any known adhesive suitable for this purpose can be used as the adhesive for use in the process according to the invention, for example hot melt adhesives, pressure sensitive adhesives, dispersion adhesives.
  • the latter can be applied as an aqueous dispersion or in an organic solvent.
  • Acrylic-based adhesives are dispersed or emulsified, for example methacrylic acid esters such as isoamyl acrylate or N-butyl acrylate.
  • hotmelt adhesives is also possible, the nozzles or the nozzle block and possibly also the feed device for the adhesive having to be heatable for this purpose.
  • Such hot melt adhesives are known, formulations based on polyolefins, for example polyethylene, polyesters but also polyamides, but especially their copolymers, having proven particularly useful.
  • Adhesives for example behenic acid etc.
  • the viscosity of the adhesive should generally be 1,000 to 70,000 mPas; especially for pressure-sensitive, removable labels, adhesive of 10,000 to 25,000 mPas should be used.
  • the spacing of the raster points across and along the direction with which the substrate is guided under the nozzles or the nozzle block can advantageously be controlled by two parameters. It corresponds to the distance of the adjacent adhesive spots across the substrate to the distance of the nozzle openings, preferably in the range of 250 to 1500 microns, particularly preferably 250 to 400 microns, while the distance of the adhesive spots in the longitudinal direction expediently by the ratio of the feed rate of the substrate to the feed rate of the bands with recesses can be determined.
  • both speeds are the same and the recesses on the belt are at the same distance as the nozzle openings, a regular grid is created in which all the adhesive points are at the same distance from one another.
  • a change in the speed of the band provided with recesses causes a change in the spacing of the adhesive points in the feed direction of the substrate. All variations are possible from distance 0 (continuous bead) to an arbitrarily wide distance, but a distance of 250 to 1,500 ⁇ m is preferred, particularly preferably 250 to 350 ⁇ m.
  • the substrate can be provided with different adhesive strength and releasability in these directions.
  • a particular advantage of the invention is that only the amount of adhesive that is also applied is always supplied.
  • the problem of residues in the screen that occurs during screen printing, which harden particularly when it is at a standstill, does not arise with the non-contact coating process.
  • the nozzle openings are flushed out by the adhesive that escapes under pressure and there is no clogging after the production has stopped.
  • the coating method according to the invention also does not include air or bubbles in the adhesive.
  • the adhesive is only in contact with the environment immediately before being applied to the carrier. Changes due to them, especially air pockets, are therefore excluded. There is no need to add an anti-foaming agent to the adhesive.
  • the printing speed is not limited and can advantageously be up to 400 m / min, particularly preferably 150 to 300 m / min.

  • a band 5 provided with recesses is guided around the nozzle block, the openings being made in a line parallel to the longitudinal axis of the band.
  • a guide device (guide groove) for the band provided with recesses ensures that it is pressed so firmly against the nozzle openings 7 that no adhesive can escape between the band and the nozzle opening.
  • the band 5 provided with recesses is guided past the nozzle openings 7, so that the alternating appearance of open and closed surfaces in front of the nozzles opens and exits or closes adhesive.
